The Dangers of Exposure to Asbestos

Asbestos was used in a variety of commercial products prior to when it was banned. According research, exposure to asbestos can cause cancer and many other health problems.

It is impossible to determine if a product is asbestos-containing by looking at it, and you are unable to smell or taste it. It is only discovered when materials containing asbestos are chipped, drilled or broken.

Chrysotile

At its peak, chrysotile made up for 95% of the asbestos made. It was employed in a variety of industries including construction, insulation, and fireproofing. If workers were exposed to this toxic material, they could develop mesothelioma and other asbestos-related diseases. Thankfully, the use this toxic mineral has decreased dramatically since mesothelioma awareness began to increase in the 1960's. It is still found in a variety of products we use today.

Chrysotile is safe to use when you have a thorough safety and handling plan in place. Personnel handling chrysotile aren't at risk of being exposed to a high degree of risk based on the current safe exposure levels. Lung cancer, lung fibrosis and mesothelioma have all been found to be strongly connected to breathing in airborne respirable fibres. This has been proven for both intensity (dose) and time span of exposure.

In one study, mortality rates were compared between a manufacturing facility that used a large proportion of chrysotile in the manufacture of friction materials and national death rates. The study concluded that, after 40 years of converting low levels of chrysotile, there was no significant increase in mortality at this factory.

As opposed to other forms of asbestos, chrysotile fibres tend to be smaller. They can penetrate the lungs, and enter the bloodstream. This makes them much more prone to causing health consequences than longer fibres.

When chrysotile is mixed with cement, it's extremely difficult for the fibres to become airborne and pose any health risks. Fibre cement products are used in many parts of the world, including schools and hospitals.

Research has revealed that amphibole asbestos such as amosite or crocidolite is less likely to cause disease. These amphibole varieties are the main cause of mesothelioma and other asbestos-related diseases. When chrysotile and cement are mixed and cured, a tough and flexible material is created that is able to withstand extreme environmental hazards and weather conditions. It is also easy to clean after use. Asbestos fibres can be easily removed by a professional and safely taken away.

Amosite

asbestos settlement is a category of silicate fibrous minerals that are found naturally in specific kinds of rock formations. It is divided into six groups which include amphibole (serpentine) and tremolite (tremolite) anthophyllite (crocidolite) and anthophyllite.

Asbestos minerals consist of long, thin fibers that range in length from fine to wide. They can also be straight or curled. These fibers are found in nature in bundles or as individual fibrils. Asbestos minerals can also be found in powder form (talc) or mixed with other minerals and sold as talcum powder and vermiculite which are widely used in consumer products such as baby powder cosmetics, face powder, and baby powder.

Asbestos was extensively used in the early two-thirds of the 20th century for construction of ships as well as insulation, fireproofing and various other construction materials. The majority of occupational exposures to asbestos fibres occurred in the air, but some workers were also exposed to asbestos-bearing rocks and contaminated vermiculite. Exposures varied by industry, time period, and geographic location.

The majority of occupational exposures to asbestos were due to inhalation. However, some workers were also exposed through contact with skin or by eating food contaminated with asbestos. Asbestos is now only found in the natural weathering of mined ores and deterioration of contaminated products like insulation, car brakes and clutches, and floor and ceiling tiles.

It is becoming clear that non-commercial amphibole fibers can also be carcinogenic. These fibers aren't knit like the fibrils found in serpentine and amphibole, but are instead loose, flexible, and needle-like. These fibres are found in the cliffs and mountains from a variety of countries.

Asbestos gets into the environment primarily as airborne particles, but it also leaches into soil and water. This occurs both from natural (weathering and erosion of asbestos-bearing rocks) and ananthropogenic (disintegration and disposal of asbestos-containing wastes in landfill sites) sources. Asbestos contamination of surface and ground water is largely associated with natural weathering, however it has also been caused by anthropogenic activities such as mining and milling demolition and dispersal asbestos-containing materials, and the removal of contaminated dumping soil in landfills (ATSDR 2001). Exposure to asbestos-containing airborne fibers is the primary cause of illness in people exposed to Asbestos attorney in the workplace.

Crocidolite

Exposure to asbestos litigation through inhalation is the most frequent method by which people are exposed to the harmful fibres, which could then enter the lungs and cause serious health problems. These include asbestosis and mesothelioma. The exposure to asbestos fibres could occur in different ways, like contact with contaminated clothes or building materials. This type of exposure is more hazardous when crocidolite (the blue asbestos form) is involved. Crocidolite is a smaller, more fragile fibers that are easy to inhale and can lodge deeper in lung tissue. It has been linked to a higher number of mesothelioma related cases than any other form of asbestos.

The six major types of asbestos are chrysotile, amosite, epoxiemite, tremolite, anthophyllite and actinolite. Chrysotile and amosite are among the most frequently used types of asbestos, and comprise 95% of commercial asbestos that is used. The other four asbestos types aren't as widespread, but they can still be present in older structures. They are less harmful than amosite and chrysotile, however they could pose a threat when mixed with other asbestos minerals or when mined in close proximity to other naturally occurring mineral deposits, such as vermiculite or talc.

Numerous studies have revealed an association between exposure to asbestos and stomach cancer. A number of studies have confirmed that asbestos exposure is linked to stomach. However there is no conclusive evidence. Certain researchers have reported an SMR (standardized mortality ratio) of 1.5 (95 percent of the time CI: 0.7-3.6) for all workers exposed to asbestos, while others have reported an SMR of 1.24 (95% of the CI = 0.76-2.5) for those working in chrysotile mines and mills.

IARC the International Agency for Research on Cancer has classified all kinds of asbestos carcinogenic. All kinds of asbestos may cause mesothelioma as well as other health issues, but the risk is dependent on the amount of exposure individuals are exposed to, the kind of asbestos involved and the duration of their exposure and the method by which it is inhaled or consumed. IARC has declared that the best option for individuals is to stay clear of all forms of asbestos. If someone has been exposed to asbestos in the past and are suffering from a disease such as mesothelioma or other respiratory ailments and require advice, they should seek out guidance from their GP or NHS 111.

Amphibole

Amphiboles comprise a variety of minerals that form prism-like or needle-like crystals. They are a type of silicate mineral composed of double chains of molecules of SiO4. They have a monoclinic arrangement of crystals, but some exhibit an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains consist of (Si,Al)O4 Tetrahedrons that are joined in rings of six. The tetrahedrons are separated from each other with octahedral strips.

Amphibole minerals are prevalent in metamorphic and igneous rocks. They are usually dark-colored and are hard. They can be difficult to distinguish from pyroxenes because they have similar hardness and color. They also share a similar Cleavage. Their chemistry can allow for a range of compositions. The different mineral groups within amphibole are identified by their chemical compositions and crystal structures.

Amphibole asbestos comprises chrysotile and the five asbestos types amosite anthophyllite (crocidolite), amosite (actinolite) and amosite. While the most popular form of asbestos is chrysotile each type has its own unique characteristics. Crocidolite is the most dangerous asbestos type. It contains sharp fibers that are easily breathed into the lung. Anthophyllite is a brownish to yellowish color and is made primarily of magnesium and iron. The variety was used previously in cement and insulation materials.

Amphiboles are a challenge to analyze because of their complex chemical structure and numerous substitutions. Therefore, a detailed analysis of their composition requires special methods. The most common methods for identifying amphiboles is EDS, WDS, and XRD. However, these methods only provide approximate identifications. For instance, these techniques cannot differentiate between magnesio-hastingsite and magnesio-hornblende. In addition, these techniques can not distinguish between ferro-hornblende or pargasite.
